Abstract
One end portion of a lug detecting lever or cassette detecting lever is arranged at the position of a safety lug of a cassette loaded on a tray unit or at the position of the cassette. The pivotal position of the other end portion of this detecting lever is varied in accordance with the presence/absence of a safety lug or a cassette. During insertion of the tray unit into a housing, a shutter mechanism is rendered operative or inoperative in accordance with the pivotal position of said detecting lever. The shutter mechanism is associated with a tape end detecting element. Upon receiving a detection signal from this tape end detecting element, a controller can determine the presence/absence of a safety lug or a cassette.
